Genome-wide population structure. (A) Eigenvalues of the 15 principal components of the genomic PCA based on 4’713 SNPs. (B–D) Position of the 256 individuals in the genomic space from the principal component analysis (PCA) performed on their genotypes (GT). The label of the population is shown on their centroid. Polygons linking outer points of the scatter plot are displayed for all populations. The legend colours are indicated in the bottom of the figure
